Serbia secures a US sanctions waiver for Russian-owned NIS oil firm, preserving the country's energy security amid complex geopolitical pressures

Serbia has secured a waiver from the United States covering NIS, its Russian-owned oil company, according to the country's energy minister. The waiver is significant because NIS has a major Russian shareholder, exposing the company to potential secondary sanctions (measures that penalise non-US entities for doing business with sanctioned parties) under US sanctions frameworks targeting Russian energy interests. The waiver allows Serbia to continue operating NIS without triggering US sanctions exposure for itself or for third-party companies that do business with NIS, at least for the duration of the waiver period. Energy security is the stated rationale: NIS is a critical component of Serbia's domestic fuel supply and refining capacity, and a forced divestiture or sanctions freeze would have created an immediate supply crisis. For international commercial lawyers, the case illustrates how OFAC (the US Treasury's Office of Foreign Assets Control, the primary US sanctions enforcement body) manages the tension between sanctions policy objectives and allied-country energy security interests through discretionary waiver mechanisms rather than blanket rules. It also highlights the due diligence obligations that non-US acquirers and business partners face when dealing with entities that have Russian state or oligarch ownership, given that strict liability applies to sanctions violations regardless of intent. Serbia's position, as a European country with deep energy ties to Russia seeking EU accession, makes the waiver diplomatically sensitive.
